 * This code implements the MD5 message-digest algorithm. The algorithm is due
 * to Ron Rivest and is described in RFC 1321.
 *
 * This code was written by Colin Plumb in 1993; no copyright is claimed.
 *
 * To compute the message digest of a chunk of bytes, declare an MD5_Context
 * structure, pass it to OI_MD5_Init, call OI_MD5_Update as needed on buffers full of
 * bytes, and then call OI_MD5_Final, which will fill a supplied 16-byte array with
 * the digest.
